Embodiment Construction
[0023]FIG. 1 illustrates an auxiliary lighting system 10 according to the present invention. The auxiliary lighting system 10 includes a photoelectric collector 12 positioned in such a manner as to receive a maximal amount of sunlight. If the auxiliary lighting system is to be used indoors, the collector could be placed indoors, in a place where it will be exposed to light, or it can be placed outdoors. The photoelectric collector 12 is then connected to an auto-switching energy sensor 14. The sensor 14 is then connected to one or more electrical storage devices 16. The storage devices 16 can then be connected to one or more LEDs 18 as the light source of the auxiliary lighting system 10. The sensor 14 can also provide an additional electric pathway directly from the photoelectric collector 12 to the LEDs 18.
[0024]FIG. 2 illustrates a modification of the present invention, shown as the auxiliary lighting system 20. In this embodiment, the photoelectric collector 12 is connected to t...

Abstract
An auxiliary lighting system contains at least one photoelectric cell to convert ambient light into energy and at least one light emitting diode. The photoelectric cell converts ambient light into energy which is stored in a storage cell. A switching system provides energy from the storage cell to the light emitting diode upon certain conditions, generally by time or by lack of ambient light.
